Fourier spectral method can achieve exponential accuracy both on the approximation level and for solving partial differential equations if the solutions are analytic. For a linear partial differential equation with a discontinuous solution, Fourier spectral method produces poor pointwise accuracy without post-processing, but still maintains exponential accuracy for all moments against analytic ...

The outcome in metastatic renal cancer remains poor with an overall survival at 5 years of less than 10%. However, molecular pathology in kidney cancer has developed extensively in the few last years, providing a basis for new systemic therapies including antiangiogenic drugs and mTOR inhibitors. Use of these targeted therapies in metastatic disease has improved the prognosis but still in a too...

Objective: The posterior reversible encephalopathy syndrome (PRES) is a clinical and radiological entity. Methods: We present a patient with predialysis CRF and PRES. Patient: A 16-year-old man with predialysis CRF admitted with headache and confusion to emergency clinic. Cranial and diffusion magnetic resonance imaging (MRI) were studied and PRES signs were seen in the bilateral parieto-occipi...

Background: Real-time monitoring of chronic lymphocytic leukemia (CLL) is crucial for effective patient management. Peripheral blood (PB) the preferred source obtaining CLL cells due to its ease access and lower cost. However, traditional methods evaluating PB films have several drawbacks, such as lack automation, reliance on personal experience, low repeatability reproducibility. To address th...

Background: Malpractice litigation continues to be a serious problem in neurosurgery despite many www.surgicalneurology-online.com 0090-3019/$ – see fro doi:10.1016/j.surneu.2 suggestions to contain liability, including proposed federal legislation. Methods: A current study of 275 malpractice claims has been compared with a prior study of 300 cases of liability and potential liability reported ...

We discuss the dynamics and thermodynamics of particle and D-brane probes moving in non-extremal black hole/brane backgrounds. When a probe falls from asymptotic infinity to the horizon, it transforms its potential energy into heat, TdS, which is absorbed by the black hole in a way consistent with the first law of thermodynamics. We show that the same remains true in the near-horizon limit, for...

When one considers the e ect in the physical space, Daubechies-based wavelet methods are equivalent to nite di erence methods with grid re nement in regions of the domain where small scale structure exists. Adding a wavelet basis function at a given scale and location where one has a correspondingly large wavelet coe cient is, essentially, equivalent to adding a grid point, or two, at the same ...

OBJECTIVE To analyze patients who underwent thoracotomy for the treatment of chest trauma in the City of Manaus. METHODS We performed a retrospective study through analyzed records in the two main reference hospitals for trauma adults in this city during a period of 5 years. We considered for this study the epidemiological data, causal agent, type of incision, anatomical classification score ...
